149 (K321) timing sight hole
 

I GIVE UP! Ive looked and looked and read and read. I am looking for the timing sight hole on my early 149 with the k321 engine. All I can seem to find is two crescent shaped cut outs behind the s/generator. Ive taken some of the tin off and found what I believe to be the T stamp on the back of the flywheel but am unble to see it thru the timing hole. Im not sure if im looking in the right place. :bash2:Any help would be greatly appreciated.

There is a thread about setting the points,http://www.onlycubcadets.net/forum/s...ead.php?t=4405

I don't know if this link works, but it is in the technical library, second page. I tried this, but not sure which one of the "lines" on the flywheel you line up. It got late and I gave up, couldn't see with a drop light, a flashlight might be a better option. I am new to these so I have yet to see a flywheel without a cover on it. Not sure this will help.

Matt's guide is awesome and should be able to help you. There is a picture of the timing sight hole in his guide (page 3). The timing sight hole should be about level with the frame on a 149. Your timing sight hole still might have the plug in it so check for a plug. I'm assuming that you've had the fly wheel cover off. The plug will be easier to see from the inside but it can still be located from the outside. Get some white paint or white out and mark that S it'll make your job easier when you go to set your timing. I had to lightly sand my flywheel to find my timing marks on my 241.

Keep us updated.

There are about 4 possible locations for the sight hole. I should update my file with pictures of all of them. Unfortunately, I don't have engines with all of the variations anymore.

The tractor in my how-to is a QL, which has a unique location for the sight hole. On a 149 it *should* be either in the half-moon shaped cutout in the bearing plate on the S/G side, or there is a sheet metal decorative cover plug in a hole on the flywheel shroud on the right side. The marks may be hard to read. You'll need a flashlight to find them. When you find them, clean them up a bit with some sandpaper and then rub some paint into the marks so you can see them more clearly.

If you post a pic of the right side of the engine, we might be able to point it out to you.

On my 128 the site hole on the flywheel shroud is on the S/G side and almost level with the top of the frame. I could see how two people might be needed to set the timing in an efficient manner.

Timing hole..149
 

on my 149 the timing hole is on the right side(S/G side). If you put a pencil under the S/G mounting bracket (also parallel to the length of the bracket)and slide the pencil rearward, the pencil will almost go into the sight hole.

From the rear screw head holding the S/G mounting bracket, go down about an inch and rearward about 2"

hope yours is like this

Took me forever to find this with the engine removed!
You can see the S/G bracket mount hole forward of the sight hole in the bearing plate.

Marks are "0C" and "SP"

My k341 on my 169 didn't have a hole at all, no idea how they timed it at the factory. I ended up drilling a 1/2 inch hole at this exact location. Thanks for the photo!
